WARNING
• Make sure the PV array is well insulated to ground before connecting it to the
inverter.
• Make sure the maximum DC voltage and the maximum short circuit current of any
string never exceed inverter permitted values specified in "Technical Data".
• Check the positive and negative polarity of the PV strings, and connect the PV
connectors to corresponding terminals only after ensuring polarity correctness.
• During the installation and operation of the inverter, please ensure that the positive
or negative electrodes of PV strings do not short-circuit to the ground. Otherwise,
an AC or DC short-circuit may occur, resulting in equipment damage. The damage
caused by this is not covered by the warranty.
• Electric arc or contactor over-temperature may occur if the DC connectors are not
firmly in place, and the loss caused is not covered by the warranty.
• If the DC input cables are reversely connected or the positive and negative termi
nals of different MPPT are shorted to ground at the same time, while the DC switch
is in the "ON" position, do not operate immediately. Otherwise, the inverter may
be damaged. Please turn the DC switch to "OFF" and remove the DC connector to
adjust the polarity of the strings when the string current is lower than 0.5 A.
• Use the DC connectors supplied with the product for DC cable connection. Using
incompatible DC connectors may result in serious consequences, and the device
damage is not covered under warranty.
• Inverters do not support full parallel connection of strings (Full parallel connection
refers to a connection method in that strings are connected in parallel and then
connected to the inverter separately).
• Do not connect one PV string to multiple inverters. Otherwise, the inverters may
be damaged.
• If AC wiring is to be performed when the inverter is connected to the grid, ensure
the DC switches are set to "OFF" to guarantee the construction safety.
NOTICE
The following requirements about PV string connection must be met. Otherwise, it
may cause irreversible damage to the inverter, which is not covered by the warranty.
• Mixed use of PV modules of different brands or models in one MPPT circuit, or PV
modules of different orientation or inclination in a string may not damage inverter,
but will cause system bad performance!
